Decoding voluntary movements and postural tremor based on thalamic LFPs as a basis for closed-loop stimulation for essential tremor
High frequency Deep brain stimulation (DBS) targeting motor thalamus is an effective therapy for essential tremor (ET). However, conventional continuous stimulation may deliver unnecessary current to the brain since tremor mainly affects voluntary movements and sustained postures in ET.Subthalamic nucleus deep brain stimulation reduces freezing of gait subtypes and patterns in Parkinson's disease
Freezing of gait (FOG) is a specific gait disorder in Parkinson's Disease (PD). FOG occurs mainly in the medication-off state and usually improves with dopaminergic medication. FOG episodes can be clinically grouped into three patterns (small steps forward, trembling in place, complete akinesia) and five provoking subtypes (starting to walk hesitation, moving in tight quarters hesitation, reaching destination hesitation, turning hesitation, and walking in open space hesitation) [1]. FOG is a debilitating symptom, limiting activities of daily living, leading to falls or fall-related injuries, and diminishing quality of life [2].Non-motor outcomes of subthalamic stimulation in Parkinson's disease depend on location of active contacts
Subthalamic nucleus (STN) deep brain stimulation (DBS) improves quality of life (QoL), motor, and non-motor symptoms (NMS) in Parkinson's disease (PD). Few studies have investigated the influence of the location of neurostimulation on NMS.Short-term quality of life after subthalamic stimulation depends on non-motor symptoms in Parkinson's disease
Subthalamic nucleus (STN) deep brain stimulation (DBS) improves quality of life (QoL), motor, and non-motor symptoms (NMS) in advanced Parkinson's disease (PD). However, considerable inter-individual variability has been observed for QoL outcome.Beneficial Effects of Bilateral Subthalamic Stimulation on Non-Motor Symptoms in Parkinson's Disease
Subthalamic nucleus (STN) deep brain stimulation (DBS) is well established for the symptomatic treatment of Parkinson's disease (PD) improving motor symptoms, activities of daily living (ADL), and quality of life (QoL) [1–3]. Non-motor symptoms (NMS) play a crucial role for QoL in patients with PD [4,5]. Long-term effects of DBS on neuropsychological [6,7] and neuropsychiatric symptoms [8,9] have been studied. However, these symptoms contribute only to a part of NMS in patients with PD. Previously published studies on a wider range of NMS have methodological limitations due to a lack of objective clinician-based [10], patient-based [11,12] or any validated assessment at all [12], and small cohort sizes of only 10 [13,14] or 11 subjects followed up on 6 month [12].Verbal Fluency in Essential Tremor Patients: The Effects of Deep Brain Stimulation
To assess the effects of different frequencies of thalamic Deep-Brain-Stimulation (DBS) on cognitive performance of patients suffering from Essential Tremor (ET).
